Abstract (en)
A system and method for improving separation by distillation in a distillation system (10) comprising a main distillation zone (20) and at least one sidestream separation zone (30) is described. According to the improved system and method, vapor separated in the sidestream separation zone (30) is passed or returned (34) to the main distillation zone (20) at a location at least two trays and/or at least one theoretical stage above the liquid draw-off from the main distillation zone (20) to the sidestream separation zone (30).
